All credit, but she is a mere Spring Chicken...
There was I believe in South London / Sussex a group called the "Midweek Wayfarer's who numbered several octogenarians, a couple of nonagenarians and a few "youngsters" in their 70's.
I was priveleged to meet the late Ron Beams on several occasions. Ron sadly died before his 100th Birthday, but was still cycling at 99. A real "Gentleman of the Road" and a superb advocate for cycling especially HPVs
As I have always said - if you think there is a risk to your health form cycling look at the age of the obituary column in the CTC magazine.
A quick google has come up with a couple of photos..
